Resumo

Abstract The essential oil from leaves of Bauhinia acuruana Moric was obtained by hydrodistillation and analyzed by gas chromatography (GC-FID) and gas chromatography/mass spectrometry (GC/MS). In total, thirty compounds comprising 91.4% of the total peak area were identified. The main constituents of the essential oil were the sesquiterpenes spathulenol (23.4 ± 0.08%), epi-α-cadinol (20.7 ± 0.12%) and caryophyllene oxide (16.4 ± 0.04%). The essential oil was tested against Aedes aegypti larvae and showed LC50 value of 56.2 ± 0.4 μg/mL.
